A GPS Monitoring System: Concept, Implementation and Experiences

Herbert Landau, Robert Hundt, Achim Mueller

Abstract:	Global Positioning System users require, even in differential applications, knowledge about the system status and health situation. GPS Information Centers with bulletin board systems have been setup all over the world to distribute such information. Most of these systems distribute second hand information received from other information centers. The system presented in the paper is designed to provide independent information on the GPS system. The GPS monitoring system consists of different parts which perform the functions: Monitoring, Data Archiving, Report Generation, Data Handling, Data Processing and Information Distribution. The monitoring component reports about satellite failures, SA-levels and ionospheric disturbances. The hard- and software components are described in detail. The service setup and the experiences made so far with the system are reported. The system concept is hardware independent and is currently available for all major receiver types.
